Studio design planning: six mistakes we keep seeing and how to avoid them

Drawing the floor plan before the programme is defined

The most frequent mistake starts before any line is drawn. A team asks for a studio and describes it by size, when the useful description is what will happen in it. A daily news bulletin, a two-camera interview show and a studio used for live conference links need different amounts of clear floor, different standing positions and different distances between set and gallery.

When the programme is vague, the plan drifts towards a compromise that suits nothing well. Sets end up pushed against a wall because the room was sized around the empty space rather than around the work, and presenters inherit awkward walking routes.

We avoid this by asking for a written list of formats first, with the number of people on the floor, the number of cameras and how often the set changes. That list becomes the brief for every later decision, and it is far cheaper to argue over than a drawing.

• List every format the studio must host
• Count people on the floor, not just presenters
• Note how often sets are struck and rebuilt

Ignoring sightlines until the cameras arrive

A floor plan can look generous and still fail at the camera. Sightlines are the lines between each camera position, the talent and the backgrounds, and they are easy to overlook on a flat drawing. A pillar, a door or a low ceiling beam that seems harmless in plan can block a wide shot or force a pedestal into an awkward position.

We check sightlines by marking each camera position and drawing the field of view for the lenses the team expects to use, then walking the same lines in the real room where possible. Cross shots matter as much as the main one, because one camera often ends up in another's frame.

The fix is simple but needs doing early: confirm lens choices in outline, draw the angles, and move the set or the camera, not the wall, while the plan is still paper.

• Draw the field of view for each planned lens
• Check that cameras do not appear in each other's shots
• Look for pillars, beams and doors that cut a line

Treating cable routes as something to sort out later

Cabling is rarely exciting, which is why it is often left until the end of a project. By then the floor boxes have been placed where the flooring contractor found it convenient, and the runs to the gallery cross walkways or share a tray with mains power. Audio picks up hum, and crew trip over what could have been hidden.

A better habit is to treat the cable route as part of the plan from the first draft. Decide where the floor boxes sit relative to each camera position and set area, how signal and power are separated, and where the main routes enter the gallery.

We also leave spare capacity. A tray that is full on day one has no room for the extra camera or monitor the team will want within a year, and retrofitting cable in a working studio is slow and disruptive.

• Place floor boxes against camera and set positions
• Keep power and signal runs apart
• Leave spare tray and conduit capacity

Forgetting the gallery and the people who work in it

Plans often concentrate on the studio floor and give the gallery whatever space remains. Yet a gallery holds the director, vision mixer, sound operator and often a producer, all working under pressure and needing to see each other, the monitors and the floor.

Common problems are desks set too close together, monitor walls that sit too high, and no clear view or talkback route to the floor manager. Heat and noise from equipment racks placed inside the room add to the strain over a long shift.

We lay out the gallery by following a typical show: who speaks to whom, who needs to see which screen, and where a visitor can stand without being in the way. Racks go in a separate machine area where possible, and the gallery gets proper ventilation before it gets decoration.

• Map who talks to whom during a live show
• Keep racks out of the working room where possible
• Give the floor manager a clear route to the gallery

Leaving out lighting, acoustics and power headroom

A studio is more than its layout. Ceiling height decides whether a lighting grid is usable at all, and a plan that ignores the grid leaves the lighting team working around fixed obstacles. Air conditioning ducts and sprinkler heads need agreeing with the grid positions early.

Acoustics are another quiet failure. Hard walls and a bare floor give a room that sounds fine to the eye and poor on the microphone, and treating it afterwards costs more than allowing for it in the design. Noisy ventilation is a related problem that only shows once the room is in use.

Power and cooling headroom is the third item. Lamps, cameras and racks add up, and a supply sized for the opening day has no margin. We ask for the expected load, add an allowance, and flag the figure to the electrical contractor in writing.

• Agree the lighting grid with ducts and sprinklers
• Plan for room acoustics and ventilation noise
• Size power and cooling with a margin for growth

Skipping the review before anything is built

The last mistake is moving to construction without a proper walk-through of the plan. Once walls, floors and trays are in, changes are expensive and sometimes impossible. A short review with the people who will use the room catches most of what drawings hide.

We run this review with the producer, the studio manager, a camera operator and the sound lead where possible, and talk through a typical show from arrival to wrap. Each person tends to spot something different: a trolley route, a missing socket, a door that opens into the set.

Write down the changes, update the drawings and have the same people sign off the revised version. It takes an afternoon and regularly saves weeks on site later in the project.

• Involve the people who will actually use the room
• Walk through a typical show from arrival to wrap
• Update the drawings and get a written sign-off

Most of these mistakes come from the same place: treating the plan as a drawing instead of a rehearsal of the work. If you describe the programme properly, check sightlines, route cables early, respect the gallery, allow for lighting, sound and power, and review before building, a studio tends to behave on its first day as it did on paper. The earlier these questions are asked, the cheaper the answers are.
